A key committee of the Parliament of Australia has recommended ratifying a new defence treaty with Papua New Guinea, a move that would elevate the relationship to a formal alliance.
The Joint Standing Committee on Treaties (JSCOT) tabled its report backing the Papua New Guinea-Australia Mutual Defence Treaty, known as the Pukpuk Treaty, describing it as a major step in strengthening ties between the two countries.
“The Pukpuk Treaty marks a significant achievement in Australia’s relationship with Papua New Guinea. This Treaty ties our two countries closer together and enables enhanced diplomatic and defence coordination and collaboration,” said Committee Chair, Lisa Chesters.
“Papua New Guinea is one of Australia’s most important partners and we are proud to call them our ally,” she said.
Once ratified, the treaty will become Australia’s third formal alliance, following the long-standing ANZUS Treaty signed more than 70 years ago.
The committee said the agreement will deepen defence cooperation, including joint training and skills exchange between the two countries’ militaries.
During its inquiry, the committee heard evidence highlighting mutual benefits such as specialised jungle warfare training and improved interoperability between forces.
The report found the treaty aligns with Australia’s broader strategic focus in the Pacific, particularly in strengthening partnerships, supporting regional stability and reinforcing sovereignty.
If approved, the Pukpuk Treaty is expected to significantly expand defence and security cooperation between Australia and Papua New Guinea, marking a new phase in their bilateral relationship.
